The basic contents of the concept of measuring instrument include:
accuracy, error, measuring standard equipment, length measurement,
Angle measurement, shape measurement, traditional optical
instrument. Applications in precision measurement and so on.
There are two kinds of measuring instruments: contact test and
optical test. Contact test: general measuring tool and 3D measuring
tool (CMM is also called cubic dimension). CMM is also called cubic
dimension, which can measure many complex spatial dimensions, such
as mold and automobile products.

2. Certification services
CCC, CQC, CQM, CB, CE, GS, EMF, ErP, UL, ETL, FCC, CEC, DOE, SAA,
RCM
We are committed to the testing and international certification of
information technology, audio and video, home appliances, lamps,
wireless communications, power tools and machinery, electronic
instruments, medical instruments and other types of products. We have obtained the qualification recognition of UL, Intertek,
CSA, MET, TUV-RH, TUV-SUD, SGS, NEMKO, FCC, IC and many other
international certification bodies. We can provide customers with
professional and authoritative one-stop testing and certification
services.
The test report issued by Global Zhongyi has legal effect and can
be used in scenarios such as the entry of supermarkets, product
appeals, anti-malicious rights protection, and auctions (appeals
and auctions must meet Party A's testing requirements).
